This changeset is motivated by a simple concept - get rid of the MiniYaml.Clone and MiniYamlNode.Clone methods to avoid deep copying yaml trees during merging. MiniYaml becoming immutable allows the merge function to reuse existing yaml trees rather than cloning them, saving on memory and improving merge performance. On initial loading the YAML for all maps is processed, so this provides a small reduction in initial loading time.
The rest of the changeset is dealing with the change in the exposed API surface. Some With* helper methods are introduced to allow creating new YAML from existing YAML. Areas of code that generated small amounts of YAML are able to transition directly to the immutable model without too much ceremony. Some use cases are far less ergonomic even with these helper methods and so a MiniYamlBuilder is introduced to retain mutable creation functionality. This allows those areas to continue to use the old mutable structures. The main users are the update rules and linting capabilities.
The ping/pong orders are replaced with a dedicated
(and much smaller) Ping packet that is handled
directly in the client and server Connection wrappers.
This allows clients to respond when the orders are
processed, instead of queuing the pong order to be
sent in the next frame (which added an extra 120ms
of unwanted latency).
The ping frequency has been raised to 1Hz, and pings
are now routed through the server events queue in
preparation for the future dynamic latency system.
The raw ping numbers are no longer sent to clients,
the server instead evaluates a single ConnectionQuality
value that in the future may be based on more than
just the ping times.
The previous asynchronous approach did not work particularly well,
leading to large janks when switching to custom maps or opening the
mission browser.
This commit introduces two key changes:
* Rule loading for WorldActorInfo and PlayerActorInfo is made
synchronous, in preparation for the next commit which will
significantly optimize this path.
* The full ruleset loading, which is required for map validation,
is moved to the server-side and managed by a new ServerMapStatusCache.
The previous syntax check is expanded to include the ability to run
lint tests.
*Remove internal GameSpeed defaults
Enforce setting values explicitly all the time
Require definition of a DefaultSpeed
*Remove Global.Timestep default
*Remove the hacky Timestep/OrderLatency setting via LobbyInfo
*Fix shellmaps ignoring mod-defined gamespeeds
*Make DateTimeGlobal use the MapOptions gamespeed
Changed the Server.LockBots setting to Server.DisableSinglePlayer.
If the setting is enabled, and there is only one client in the server,
the game won't start.
